TypeError with Cospend

[arifer612]

Hi there, I have a similar issue to #79. I enabled the Cospend app and had no projects added. Not long after, I checked my logs and saw that there was a TypeError telling me that getProjectNames() returned a null (go to the bottom for an extended description of the error). I added a project titled `House renovation' but the error still popped up 15 minutes after the last one. Restarting the Nextcloud docker did nothing either.

I know that I should add a try-catch in .../www/nextcloud/apps/cospend/lib/Service/ProjectService.php from the error debug but I'm not familiar with php so I would appreciate it if somebody could help draft something up for me to use.

The debug of the error as seen in the logs:

TypeError: Argument 1 passed to OCA\Cospend\Service\ProjectService::getProjectNames() must be of the type string, null given, called in /config/www/nextcloud/apps/cospend/lib/Activity/CospendProvider.php on line 84

Oh dear, I had posted in the wrong app! I'll close this right now and raise the issue in the right app repo.
